The Networks Data Science group at IMDEA Networks Institute has an opening for one PhD student in the area of mobile network intelligence. The successful candidate will design original AI solutions for the automation of network functionalities to be deployed in next-generation 6G systems. The focus of the studies will be on surpassing practical limitations that affect today’s AI paradigms and hinder their adoption in production-grade mobile network infrastructures. The PhD student will work in the context of on-going  collaborations with leading MNOs such as Orange and Telefónica and take advantage of privileged access to Terabytes of measurements from real-world networks to (i) understand the very specific challenges of learning from network traffic, (ii) train original AI models that are designed to operate precisely on such data, and (iii) demonstrate the viability in production of AI-driven solutions for, e.g., KPI forecasting, RAN energy cost reduction, or anomaly detection—all of which are still largely open problems in 5G production networks. The NDS group has a notable history of breakthroughs in the design of AI for mobile network operation [1-12], which represents an ideal foundation for the student to make meaningful contributions to the field.
